Because if not that then it seems the real reason to play Curse of Obsession is to curse yourself and have a less killable Avaricious Dragon on your board to get some red card draw going
It started with the inclusion of foil variants, which seemed so exciting when they first came out that players would do almost anything to get their hands on them
The new cards are: Greymond, Avacyns Stalwart (previously Rick, Steadfast Leader) Hanks, Slayer Zealot (previously Daryl, Hunter of Walkers) Gregor, Shrewd Magistrate (previously Glenn, the Voice of Calm) Enkira, Hostile Scavenger (previously Michonne, Ruthless Survivor) Malik, Grim Manipulator (previously Negan, the Cold-Blooded) Gisas Favorite Shovel (previously Lucille) They will appear on The List, which is a special card slot in Set Boosters that has a 25% drop rate (meaning that approximately one in every four Set Boosters will contain a card from The List)
Perhaps this was a card pitched for Phyrexia: All Will Be One
If the creature gets killed, you lose
